The Importance of Carbon Monoxide Detectors

Imagine a killer in your home – silent, invisible, and completely odourless.

Carbon monoxide (CO) is known as the “silent killer” for good reason. You can’t see it, smell it, or taste it, but breathing it in can be fatal in minutes. Yet many homes and workplaces across the UK still don’t have a working carbon monoxide detector installed.

If that sounds risky, that’s because it is.

What is Carbon Monoxide?

Carbon monoxide is a toxic gas produced when fuels like gas, oil, wood, or coal don’t burn completely. It can build up in enclosed or poorly ventilated spaces – especially around faulty boilers, gas cookers, fires, and heating appliances.

When inhaled, CO prevents your body from absorbing oxygen properly. Even low levels can cause serious health issues. High levels can be deadly.

Symptoms of Carbon Monoxide Poisoning

One of the most dangerous things about carbon monoxide is how easily its effects can be mistaken for something else. Flu-like symptoms, tiredness, headaches, nausea, breathlessness – all common signs of exposure.

That’s why many victims don’t realise what’s happening until it’s too late.

In the UK, carbon monoxide poisoning causes around 60 deaths and 200 hospital admissions each year. These tragedies are preventable.

Why Carbon Monoxide Detectors Matter

A carbon monoxide detector is your early warning system. Just like a smoke alarm alerts you to fire, a CO detector sounds the alarm if carbon monoxide levels rise dangerously. It gives you the time you need to act: to ventilate the area, shut down faulty appliances, and evacuate safely.

More than just a safety add-on, it’s a life-saving essential.

Are Carbon Monoxide Detectors a Legal Requirement?

In many cases, yes.

For landlords in England, carbon monoxide alarms are legally required in rooms with any solid fuel-burning appliance (like a wood-burning stove or coal fire), and must also be installed when new gas appliances (excluding cookers) are fitted.

From October 2022, the law was updated to include all rooms with fixed combustion appliances, with a duty to repair or replace faulty alarms promptly.

Homeowners aren’t legally required to install one – but not having a detector puts your household at serious risk.

Where Should You Install a Carbon Monoxide Detector?

For best protection:

• Place detectors in every room with a fuel-burning appliance

• Install at head height (about 1.5m from the ground), not on the ceiling

• Avoid putting them near windows, doors, or extractor fans

• Don’t install them inside cupboards or behind furniture

It’s also wise to have detectors near bedrooms, so they can wake you if there’s a leak at night.

How to Stay Safe

• Install detectors in all the right places

• Test them monthly, just like your smoke alarms

• Replace batteries annually (or as needed)

• Replace the unit itself every 5–7 years (check the manufacturer’s instructions)

• Have your appliances serviced regularly by a Gas Safe registered engineer
